This study describes, and examines the initial efficacy of, a sleep therapy programme developed for cancer patients with insomnia. The six-session group programme included stimulus control therapy, relaxation training, and other strategies aimed at consolidating sleep and reducing cognitive-emotional arousal. The 12 final participants were patients of a regional cancer centre; mean age was 54.7 years (S.D. 10.4); median time from cancer diagnosis was 33.6 months; all had high performance status. Participants kept sleep diaries and rated their sleep quality, mood and functioning at baseline, week 4 and week 8. Significant improvement over baseline was observed at weeks 4 and 8 in the number of awakenings, time awake after sleep onset, sleep efficiency, sleep quality ratings, and scores on European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 role functioning and insomnia. Total sleep time and fatigue were significantly improved at week 8. The sleep therapy programme was associated with improved sleep, reduced fatigue and enhanced ability to perform activities in relatively well individuals attending a cancer centre. This is preliminary evidence of the efficacy of the programme. Further research is required to examine the programme's effectiveness and suitability for a wider range of people with cancer. Options for providing cancer patients with access to nonpharmacologic treatments for insomnia are discussed.

Mirtazapine is an antidepressant that has a receptor-binding profile that may suit it for use in controlling the nausea and insomnia of highly emetic cancer chemotherapy. Mirtazapine binds to and is antagonistic at the 5HT3 receptor, as are the group of medicines related to ondansetron. Mirtazapine is anxiolytic by virtue of its antagonism of the 5HT2 receptor, and is strongly sleep inducing. The resulting sleep quality tends to be superior to that induced by benzodiazapines. There has been concern about mirtazapine's potential to suppress bone marrow function, so that further study is required before routine use in chemotherapy can be adopted.

To determine the prevalence, severity, and correlates of fatigue among patients with cancers of the prostate or breast receiving high dose radiotherapy with curative intent, a prospective, questionnaire-based study evaluated a convenience sample of 62 patients who were about to start a course of radiotherapy. Patients were assessed immediately prior to treatment, and again within a week of finishing. Fatigue was assessed using the Fatigue Severity Scale (FSS) and the Bidimensional Fatigue Scale (BFS). Quality of life was assessed using the European Organisation for Research and Treatment of Cancer 30-item Quality of Life Questionnaire (EORTC QLQc30). Psychological distress was assessed using the Hospital Anxiety and Depression Scale (HADS). Personality Traits were assessed using the Eysenck Personality Inventory (EPI). Fatigue severity increased significantly on 3 out of the 5 assessment instruments used. Radiotherapy was associated with a decline in global quality of life, role, cognitive and social functioning, and an increase in nausea/vomiting, pain, insomnia, diarrhea, and financial difficulty. At baseline, 39% of the variation in fatigue scores among the patients could be explained by a combination of measures of their global quality of life and physical functioning. A combination of fatigue and anxiety scores at baseline was able to predict 54% of the variation in fatigue scores at the completion of radiotherapy. These data indicate that fatigue is a significant problem for patients receiving radical radiotherapy, although its severity is relatively modest.

Few studies have attempted to describe the experience of symptoms in young children with cancer. This is due, in part, to the lack of validated symptom assessment scales for this patient population. The objective of this study was to evaluate the reliability and validity of a revised Memorial Symptom Assessment Scale (MSAS) in patients aged 7-12 as an instrument for the assessment of symptoms in young children with cancer. The MSAS (7-12) was administered to 149 children (inpatients and outpatients) who were undergoing treatment at either the Royal Marsden NHS Trust, London, United Kingdom or The Children's Hospital at Westmead, Sydney, Australia. Validity was evaluated by comparison with the medical record, parental report, and concurrent assessment on visual analogue scales for selected symptoms. The data provide evidence of the reliability and validity of MSAS (7-12) and demonstrate that children with cancer as young as 7 years can report clinically relevant and consistent information about their symptom experience. Young children with cancer experience multiple symptoms. Approximately one-third had experienced lethargy and/or pain and/or insomnia during the 48 hours prior to the completion of MSAS (7-12). The completion rate for MSAS (7-12) was high and the majority of children completed the instrument in a short period of time and with little difficulty. The instrument appears to be age appropriate and may be helpful to older children unable to independently complete MSAS (10-18). Systematic symptom assessment may be useful in future epidemiological studies of symptoms and in cancer chemotherapy drug trials.

Exhaustion and tiredness are frequent symptoms in cancer patients. They are caused by the tumour itself and by application of chemotherapy, surgery, radiation or cytokine treatment. Exhaustion and tiredness are not a consequence of lacking sleep or exaggerated physical or mental labour, but are due to several other factors: Anemia, tumour cachexia, toxicity of chemo- and radiation treatment probably are the most decisive factors for the development of exhaustion and tiredness. As both were taken as inevitable side-effects of cancer and cancer treatment in the past, only little attention has been paid to exhaustion and tiredness and limited research has been done. Among several validated questionnaires measuring quality of life in tumour patients the FACT-An (Functional Assessment of Cancer Treatment--Anemia) and EORTC QLQ-C30 questionnaire are the most well-known for identifying exhaustion and tiredness. Nevertheless, until today there is no mere exhaustion scale exclusively dealing with the problem of exhaustion and tiredness. According to the 10th revision of the International Classification of Diseases (ICD) exhaustion and tiredness are subsumed under the diagnosis of tumour fatigue. In contrast to tumour fatigue, which comprises physical, mental and emotional dimensions, exhaustion and tiredness primarily refer to physical symptoms: Lacking resilience for activities of daily life, day sleepiness and nocturnal insomnia as well as restricted power of concentration are the mainstays of exhaustion and tiredness. However, regarding lacking interests, diminished energy and reduced mental capacity, exhaustion and fatigue partly overlap. From a therapeutic point of view behavioural interventions and drug therapy have successfully been tried. Beside physical exercise and psychostimulants application of Erythropoietin represents an innovative treatment of exhaustion and tiredness.

MBM is a well-established phenomenon in modern medicine. If one accepts a model of mind/body that is truly nondualistic, it could be said that the MBM phenomenon is inherent to medicine. Because of its popularity and efficacy for common chronic conditions, MBM may have its greatest presence in primary care medicine. The flourishing of MBM techniques resulting from the public's enthusiastic embrace of these therapies has created a great need for rigorous scientific examination. The MBM literature may be said to be in its adolescence, having grown out of its early years of enthusiastic case reports and small studies, but not yet fully grown into a broad catalogue of large controlled experimental trials. Nevertheless, clinical trials suggest that certain MBM therapies are effective in improving quality of life, anxiety, and pain intensity for a variety of conditions. There is moderate evidence to suggest these techniques improve chronic pain, headache, insomnia, and other common conditions. There is preliminary evidence to suggest these techniques may affect coronary artery disease and cancer. MBM techniques ultimately may prove to be most effective in combinations or in conjunction with traditional treatment.

Fatigue is a common complaint for the cancer patient during and after radiotherapy, according to the published studies. Fatigue is a subjective symptom mostly underestimated by oncologists and other care givers. Etiology is complex, poorly understood in spite of obvious causes like insomnia, nausea, pain, depression, psychological distress, anemia, hypothyroidism, menopause disturbances, treatment adverse effects. Fatigue presents multifactorial and multidimensional aspects. To evaluate it, many tools can be used as single-item, unidimensional and multidimensional instruments. Practically, the open discussion with the patient throughout radiotherapy is essential to define it. Taking charge fatigue requires its acknowledgment by radiotherapist, treatment of associated symptoms with a multidisciplinary approach.

We performed a pilot open-label, crossover trial of mirtazapine (15 and 30 mg at night) in advanced cancer patients with pain and other distressing symptoms. Twenty patients completed the trial and sixteen dropped out. Following a baseline assessment, patients completed a one-week observation period and were then randomized to a starting dose of either 15 mg or 30 mg of mirtazapine given at bedtime. After three weeks, subjects were switched to the alternate dose and followed by an additional three-week period, completing the treatment. The average age of the completers was 60.2 years and consisted of 7 women and 13 men. The majority were Caucasian (n = 18, 90%) and married (n = 18, 90%). The drop-out group did not significantly differ from the completers based on age, gender, race, marital status, or tumor type. We examined the impact of mirtazapine therapy on patients' levels of depression, pain intensity, appetite, insomnia, weight, and overall quality of life. A series of repeated measures ANOVAs were conducted to compare the completers' status at Weeks 1, 4, and 7 compared to baseline and to examine the interaction with starting dose and baseline observations. Scores on the Zung self-rating Depression Scale (F = 8.20, P < 0.05) and the Functional Assessment of Cancer Therapy - General Measure (F = 5.73, P < 0.05) were significantly improved at study end (Week 7) and were not dependent on mirtazapine dosage. Patients' weights were significantly higher at both Week 4 and Week 7, independent of dosage. Trend level differences were found on Memorial Pain Assessment Card items for pain, pain relief, and mood and on numeric rating scales measuring nausea, anxiety, insomnia, and appetite. This open-label pilot study suggests that mirtazapine may be effective for improving multiple symptoms, depression and quality of life in patients with advanced cancer. A controlled trial of this drug would be valuable.

Sleep difficulty is a prominent concern of cancer patients, yet there has been no large study of the prevalence and nature of sleep disturbance in cancer patients. This cross-sectional survey study examined: (a) the prevalence of reported sleep problems in patients attending six clinics at a regional cancer centre; (b) sleep problem prevalence in relation to cancer treatment; and (c) the nature of reported insomnia (type, duration, and associated factors). For three months, all patients attending clinics for breast, gastrointestinal, genitourinary, gynecologic, lung, and non-melanoma skin cancers were offered a brief sleep questionnaire. Response rate was 87%; the final sample size was 982. Mean age of respondents was 64.9 years (SD 12.5). The most prevalent problems were excessive fatigue (44% of patients), leg restlessness (41%). insomnia (31%), and excessive sleepiness (28%). Chi square tests showed significant variation among clinics in the prevalence of most sleep problems. The lung clinic had the highest or second-highest prevalence of problems. The breast clinic had a high prevalence of insomnia and fatigue. Recent cancer treatment was associated with excessive fatigue and hypersomnolence. Insomnia commonly involved multiple awakenings (76% of cases) and duration > or = 6 months (75% of cases). In 48% of cases, insomnia onset was reported to occur around the time of cancer diagnosis (falling within the period 6 months pre-diagnosis to 18 months post-diagnosis). The most frequently identified contributors to insomnia were thoughts, concerns, and pain/discomfort. In a multivariate logistic regression analysis, variables associated with increased odds of insomnia were fatigue, age (inverse relationship), leg restlessness, sedative/hypnotic use, low or variable mood, dreams, concerns, and recent cancer surgery. This study provides new information about sleep-related phenomena in cancer patients, information which will be useful in planning supportive care services for cancer patients.

Many conditions that would not be considered normal in a younger population are routinely accepted in older people as a part of so-called "normal" aging. Among these conditions are many chronic and debilitating conditions such as chronic pain, insomnia, weakness, fatigue, and anemia. This article reviews current evidence regarding the relationships among age, fatigue, weakness, anemia, and erythropoiesis. Anemia in the elderly is important because it can lead to weakness, fatigue, limitations in activity, and may increase cardiovascular risk. Recent studies of the effect of erythropoietin in an aging population support the hypothesis that anemia is associated with pathologic factors and not with normal aging. While older individuals admitted to hospitals are more likely to be anemic, these same individuals have a bone marrow mass and numbers of cultured progenitor cells that are similar to that of the younger population; therefore, the predicted response to erythropoietin, and thus the function of the bone marrow and cellular progenitors, is maintained. Thus, we can conclude that anemia is a correctable pathologic finding in elderly people. A number of studies have shown a strong relationship between fatigue and anemia, but few studies investigate to what degree age is a factor in weakness and fatigue. In a study of 375 anemic cancer patients with a median age of 61 years, age as a covariate in multiple linear regression analysis failed to reach significance for most measures of function and quality of life (QOL), including measures of energy, activities, mental health, general cancer-related QOL, and overall QOL. Additional analysis suggests that other factors, including cancer progression, hemoglobin change, and baseline hemoglobin levels, are much more important in determining change in functional and quality-of-life scores. In another set of 2,000 cancer patients and 1,000 controls, cancer patients experienced significantly more fatigue compared with controls. There was no correlation between cancer patient age and fatigue, while in controls the cohort aged 65 or more reported more fatigue than did younger subjects. Finally, measurement of QOL in the general population demonstrated, for both the Short-Form 36 and Functional Assessment of Cancer Therapy - Anemia questionnaires, that age alone is not significantly correlated with QOL. We suggest that chronic conditions such as fatigue and anemia are no more "normal" in an aging population than in a general population, and that all patients with chronic conditions be adequately treated and counseled for their condition.
